Hello Gabor,

If you could attach the following file to this ticket, it would help me reproduce this problem:

/home/gabor/Desktop/Pictures/Photos/2010/05/15/P5150003.JPG

If you would prefer not to make this photo public, you can email it to me at <email address hidden>. I'll destroy the photo once I'm done with it.

Also, I'm changing the project to gexiv2, as I believe the problem is in that library and not Shotwell proper.

Hi Jim,
I sent you the file you asked for in the e-mail privately.
Please let me know if anything else is needed from me. Also, just an information, it was a lot of pictures I wanted to import all at once. something like 20,000 pictures. This might have be part of the problem. But I could do it in the previous photo program on the same computer.

Thanks for your help.

Gabor

Hi Gabor,

I've reproduced the problem with the photo you sent me. I'll look into it soon!

[Jim Nelson (yorba-jim)]

This problem is with Exiv2. It can be reproduced with the command-line tool like this:

$ exiv2 -pp <filename>

Essentially, the crash is occurring when the preview directory is being loaded.

[Gabor Toth (gabor-me)]

okay. let me know if anything else is needed from me on this issue.

I've submitted a bug report to Exiv2: http://dev.exiv2.org/issues/739

I've verified this is fixed in Exiv2 trunk. This should be resolved in the next Exiv2 release.
